Abstract
A clip (40) adapted to attach a heat sink (30) to an electronic device (20) includes a body (50) and a lever (70). The lever is fastened to the body with a pivot (96). The lever includes a pressing portion (74) and a bore (80). First and second contact points (76, 78) are defined at a lower edge of the pressing portion at different distances from the bore. The clip is initially placed in a groove (36) of the heat sink, whereupon the first contact point abuts a top surface of the groove. When the lever is fully depressed, the second contact point firmly abuts the top surface of the groove. Thus the clip securely attaches the heat sink to the electronic device.
Claims20
A clip adapted to secure a heat sink to an electronic device retained on a socket, comprising:
- a body including a resilient portion, first and second legs depending from the resilient portion;
- a lever pivotally connected to the resilient portion of the body thereby forming a pivot point, the lever comprising a pressing portion adapted to press the heat sink to the electronic device, the pressing portion defining a first contact point and a second contact point, the distance between the first contact point and the pivot point being shorter than that between the second contact point and the pivot point;
- and
- wherein when the clip is initially placed on the heat sink, the first contact point abuts a top surface of the heat sink, and when the clip is secured to the heat sink and the socket, the second contact point firmly abuts the top surface of the heat sink;
- and
- wherein a slot is defined to pass through both the resilient portion and the second leg, for insertion of the lever therethrough.
A clip adapted to secure a heat sink to an electronic device, comprising:
- a body including a resilient portion, first and second legs depending from the resilient portion, and;
- a lever pivotally connected to the resilient portion of the body thereby forming a pivot point, the lever comprising a pressing portion adapted to press the heat sink to the electronic device, the pressing portion defining a first contact point and a second contact point, the first and second contact points being at different distances from the pivot point;
- wherein
- the pressing portion extends arcuately and downwardly from an end of the lever, and wherein the defined first and second contact points are lines.
An heat sink assembly comprising:
- a socket;
- an electronic device positioned on the socket;
- a heat sink positioned on the electronic device and defining a groove therein;
- a clip for attaching the heat sink to the socket, said clip including:
- a body defining a resilient portion, first and second legs extending downwardly from two opposite ends of said resilient portion and latchably engaged with two sides of the socket;
- and
- a moveable piece including a pressing portion positioned between the resilient portion and a top surface of the heat sink;
- wherein
- said pressing portion is actuated to be in a first position where the resilient portion is closer to the top surface of the heat sink for loosely holding the heat sink on the socket while to be in a second position where the resilient portion is farther away from the top surface of the heat sink for firmly grasping the socket by means of the legs;
- wherein
- a rod is connected between the moveable piece and one of said first and second legs to actuate said one of the first and second legs to move inwardly when said the pressing portion is in the second position.
A clip adapted to secure a heat sink to an electronic device retained on a socket, comprising:
- a body including a resilient portion, first and second legs depending from the resilient portion;
- a lever pivotally connected to the resilient portion of the body thereby forming a pivot point, the lever comprising a pressing portion adapted to press the heat sink to the electronic device, the pressing portion defining a first contact point and a second contact point, the distance between the first contact point and the pivot point being shorter than that between the second contact point and the pivot point;
- and
- wherein when the clip is initially placed on the heat sink, the first contact point abuts a top surface of the heat sink, and when the clip is secured to the heat sink and the socket, the second contact point firmly abuts the top surface of the heat sink;
- and
- wherein the clip further comprises a rod for enhancing the fixing function of the clip.
